How to watermark a PDF

Everyday uses

  • Shared copies – mark ID copies “Only for bank KYC” before sending.
  • Drafts – stamp DRAFT on documents still under review.
  • Brand your documents – add your company logo to quotations.
  • Protect notes – add your name to study material you share.

Good to know

Text in any language (Hindi, Gujarati, ₹ symbol and more) is supported. A watermark across the page discourages misuse of copies, especially of ID documents.

For an extra layer, combine it with Protect PDF so the file needs a password to open.

Private by design. Watermark PDF works inside your browser. Your file is processed on your device and is not uploaded to our server.

Limits to know before you start

  • A watermark discourages misuse but can be removed by someone determined with editing software. Combine it with Protect PDF for sensitive files.
  • The watermark is drawn on top of the page, so a dark or large watermark can make text harder to read. Lower the opacity if needed.
  • Logo watermarks look best as PNG files with a transparent background.

If something goes wrong

The tool asks for a password. The PDF is protected. Type the password you normally use to open it; it is used only in your browser. The new file is not locked.

The watermark hides the text. Lower the transparency slider or make the text smaller.

My logo has a white box around it. Use a PNG with a transparent background.

Watermark PDF – questions

How do I add a watermark to a PDF?

Can I add my logo as a watermark?

Yes. Choose “Image”, pick a PNG or JPG logo and set its size and transparency.

Can I watermark only some pages?

Yes. Enter the pages, e.g. 1-3, 7.

Can the watermark be removed later?

It is part of the page content. Simple editors cannot easily remove it, but no watermark is impossible to remove.
